海南岛砖红壤中Pb元素含量特征及环境质量评价
The Content of Pb Element and Environmental Quality Assessment in Latosol of Hainan Island
摘要
Abstract
[Objective] To research the content of Pb element in latosol of Hainan island and to assess its environmental quality. [ Method] Samples were selected for lab analysis. 27 samples from different landforms of Hainan Island were selected (the same place was sampled for three times) to analyze the content of Pb in latosol of Hainan Island, study the spatial distribution feature of this element in latosol from different places and evaluate the content of Pb element in latosol of Hainan Island by geo-accumulation index. [ Result] The content of Pb generally stays at high level in latosol of Hainan Island; however, the mean content of Pb in east Hainan is lower than the mean value of west Hainan; vertically, the mean content of Pb shows descending order from hills, mountainous area to plain; the pollution assessment result showed that latosol of Hainan Island was hardly polluted by Pb element and only its content in the latosol from middle, south area stays at high level. [Conclusion] The research provided scientific reference for constructing a national tropical modern agricultural base in Hainan as well as controlling Pb pollution.关键词
